Brick is 3" x 8" = 1/4' x 2/3' = 2/12 = 1/6 square feet To fill 75 square feet you will need (75)/(1/6) = 75 x 6 = 450

Gee, a square foot is 12x12, difficult problem.

Technically, 2.6388888888888 etc. but 3. I'm assuming the brick is 12x12 feet here as that is the only unit you have mentioned...

About 14 bricks should do it.

The surface area of a brick is therefore 16 * 16 = 256 square inches which is 256 / (12 * 12) = 1 7/9 square feet. So you will need exactly 196 / 1 7/9 = 110.25. Best make it at least 111 then.
